Got this via the new release notifier:
This version contains mainly bug fixes.

Here's the complete list:

o Fixed a threading issue in the network calendar.
o Added support for Bosnian language.
o Events defined as localtime in the ics-file were interpreted as UTC. Fixed.
o Ctrl+A works now in Manager.
o Weekdays were displayed incorrectly in vertical and horizontal calendars.
Fixed.
o Added keypad and scroll &amp; num locks to hotkey support.
o The tray tooltip is shown correctly even if the tray is outside the screen.
o Adding exceptions (i.e. deleting) recurring events from event list didn't
work. Fixed.
